It is a quite typical portuguese municipal flag, with the coat of arms
centered on a white and black quartered (town rank)
background. The coat of arms is gules, a tower argent open sable between four
bunches (?) of grapes of the same. Mural crown argent with four visible towers
(town rank) and white scroll reading in black upper
case letters "VILA DE VINHAIS". The coat of arms is partly
canting, as "vinhais" is one of many words meaning "vineyards".António Martins, 13 Jun 2000
